Core Product Summary
The Pioneer Magnetics PM3398B-6P-1-3P-E is an AC-to-DC switching power supply from the PM33xx PowerFactor series, built in the three-phase-input (3P) configuration of the PM3398 model family; units of this build carry the companion part number 80026-172-03. It accepts a 120–240 VAC input at 50/60 Hz with a 23 A input rating.
As a PowerFactor-series unit, its input stage provides power-factor correction and converts the AC line into isolated, floating DC output for downstream industrial loads. The manufacturer documents the PM33 front-end family as available in single-phase (1P) and three-phase (3P) AC input versions, with full output power delivered over a 0 °C to +50 °C ambient range, a fully floating output, and ±0.1% output voltage stability over 24 hours after a 30-minute warm-up. Overvoltage protection on the series latches a shutdown that clears after the AC line is removed for approximately 30 seconds and reapplied.

Detailed Product Overview
The PM3398B-6P-1-3P-E is the three-phase-input member of Pioneer Magnetics’ PM3398 front-end family. The manufacturer produces the PM33 front-end line in both single-phase (1P) and three-phase (3P) AC input versions, and this model’s “-6P … -3P” suffixes place it on the three-phase side of that family tree. For engineers maintaining an installed chassis, this distinction is the single most important identification point: the three-phase input build and its single-phase sibling look similar and share the PM3398B base designation, but they are wired to different supply systems and are not interchangeable replacements for one another.
The unit accepts a 120–240 VAC line at 50/60 Hz with a 23 A input rating. On a three-phase input build, this rating defines the per-phase supply capacity, upstream protection, and input conductor sizing the installation must provide. The power-factor-corrected input stage keeps harmonic current drawn from the line low, which matters where facility power-quality specifications limit input distortion.
The output side of the PM33 front-end family is a fully floating, isolated DC rail. Because Pioneer Magnetics configures output voltage and current to the individual build, the exact output values of the -6P-1-3P-E build should be confirmed from the unit’s nameplate before a replacement is ordered — the same family includes single-phase builds documented at 56 V DC, 26.8 A (approximately 1500 W), but the output values of this specific three-phase build are defined by its own configuration record. When matching a replacement to an installed chassis, use the full model number together with the companion part number 80026-172-03.
Protection behavior follows the PowerFactor series convention: an overvoltage condition latches a shutdown at approximately 125% ±5% of nominal output, and the latch clears only after AC input is removed for about 30 seconds and reapplied. Thermal performance is specified for full output power from 0 °C to +50 °C ambient, so enclosure ventilation must account for the unit’s dissipation. Output regulation is tight — ±0.1% over 24 hours after a 30-minute warm-up — which is the stability figure that matters for loads sensitive to long-term drift.

System Compatibility & Integration Requirements
| Item / Dependency | Verified Requirement | Practical Note |
|---|---|---|
| AC input supply | 120–240 VAC, 50/60 Hz, three-phase (3P) input build | Confirm the supply phases and input wiring match the three-phase build before connection |
| Input rating | 23 A | Size upstream protection and input conductors for the 23 A input class |
| Output configuration | Isolated, fully floating DC; output values per unit nameplate | Verify output voltage/current against the nameplate and configuration record before ordering |
| Build identification | Companion part number 80026-172-03 | Use full model plus companion number when matching replacements to an installed chassis |
| Installation environment | 0 °C to +50 °C ambient for full output | Include the unit’s dissipation in cabinet cooling calculations |
| Fault recovery | OVP latches until AC input is removed ~30 s and reapplied | Provide an input disconnect if rapid fault recovery is required |
| Output stability | ±0.1% over 24 h after 30-minute warm-up | Relevant when feeding loads sensitive to long-term voltage drift |
Dimensions, Mounting & Connection Notes
